Small but Powerful: Medium-Pressure UV Lamps for Searchlight Applications

Small but Powerful: Built to Specification, Proven in Performance

When people think of medium-pressure UV lamps, the expectation is typically around a standard design built for established applications. Reliable, consistent, and widely understood.

But not every requirement fits neatly into a standard format.

This project was a clear example of how adaptability and engineering expertise come together. While this type of lamp is not new to the industry, it highlights (or should we say spotlights…) a very different approach to using medium-pressure mercury based UV lamps. Developed to meet a specific customer requirement, it reflects our ability to design and produce lamps precisely to specification, without compromise.

Designed Around the Application

Created for a marine search light system, this lamp had to meet a unique set of demands. Operating at sea introduces constant vibration, exposure to harsh environments, and the need for absolute reliability.

Its compact and unconventional design sets it apart from traditional medium-pressure UV lamps, but every detail is intentional:

• Rugged construction for dependable performance
• Low power requirements suited to onboard systems
• Stable output in high stress conditions

This is not a one-size-fits-all product. It is a purpose-built solution.

Small Size. Serious Output.

Despite possibly being the smallest medium-pressure mercury lamp we currently manufacture, its performance is anything but limited.

Within the customer’s system, the lamp serves a dual role. It functions as a search light while also enabling Morse code signalling, delivering both visibility and communication in critical situations.

It also compares well against high-pressure lamps in terms of heat output, offering a more controlled thermal profile. In environments where heat management is essential, this becomes a significant advantage.

Beyond Marine Applications

Although developed for a marine use case, the characteristics of this lamp open up opportunities across other sectors.

Its compact size and high output make it suitable for:

• High resolution projection systems
• Theatre and spotlight applications
• Installations where space, power, and heat must be carefully managed

In many of these areas, high-pressure Xenon lamps are often the default choice. However, depending on the required specification, this medium-pressure alternative demonstrates that there are other options worth considering.

What This Really Represents

This project is not about introducing a new technology but it does demonstrate Alpha-Cure’s approach to lamp solutions and our collaborative capability.

The ability to take an existing lamp type, adapt it, refine it, and manufacture it to meet a precise requirement is where real value lies. It shows the strength of our R&D approach and our willingness to work closely with customers to deliver exactly what their application demands.

Small but powerful is more than a description of the lamp itself. It reflects a broader approach to engineering in Alpha-Cure
